This study aimed to evaluate the pathological factors and anatomical variations in the maxillary sinus in patients undergoing dental implant treatment using cone beam computed tomography (CBCT). CBCT, as a key imaging technique in dentistry, offers high-resolution images to assess bone morphology and quality, crucial for preoperative dental implant planning. Material and methods: The study included a cohort of 200 patients recommended for CBCT as part of their preoperative evaluation. The methodology involved detailed CBCT image analysis to identify and document various anatomical variations due to pneumatization, exostosis, hypoplasia, polyps, cysts, foreign bodies, and anthroliths within the maxillary sinus. Results: Pneumatization was the most common variation, present in 77.5% of subjects. Polypoid lesions were found in 17.5% of patients, with a higher prevalence in younger age groups (57.1% in ages 20–35). Cysts and polyps affected 17.5% of subjects, predominantly males (65.7%). Anthroliths were observed in a minimal percentage (2%), and foreign bodies were found in 1.5% of the patients. Positive correlations were observed between the patient’s age and both mucosal thickness and polypoid lesions and between the patient’s gender and bone thickening (p-values < 0.05). Conclusions: The study concluded that CBCT is essential in the preoperative assessment of the maxillary sinus in dental implant candidates due to its superior imaging capabilities, allowing for the identification of critical anatomical variations and pathologies. This thorough evaluation is imperative to ensure the success of implant placement and to mitigate potential complications. However, further research with larger, more diverse populations is recommended to confirm these findings.
